Title: Method for operating a well jet device during repair and insulating operations and device for carrying out said method
Inventor: KHOMYNETS ZINOVIY DMITRIEVICH
IPC: F04F5/46
Filed: 2002-05-30
Abstract: The inventive method consists in the following: a drillable packer provided with a channel closed by a back valve is arranged in a well; afterwards a tubing string carrying a jet pump and a stinger is run into said well, the stringer being connected to the packer; the back valve is open; a logging instrument and a sealing unit are introduced into the tubing string with the aid of a cable; a depression is produced on the formation by means of the pump, a bottomhole pressure and the parameters of the formation are measured with the aid of said instrument, the parameters of physical fields being recorded. The results of said investigations being interpreted, the technical state of the well is defined. The instrument and the sealing unit being extracted from the tube string, a blocking insert is dropped therein. The tubing string is uplifted, the stringer is disconnected from the packer and the back valve is closed. A cement slurry being pumped into the tubing string, said tubing string is put down, the stringer is connected to the packer and the back valve is open. The cement slurry is pumped into the tail space, squeezed into the productive formation and the tubing string together with the pump and the stringer is extracted. The cement slurry being hardened, the packer is drilled out, the formation is perforated and the tubing string provided with a guiding cone, the packer and the pump is brought in the well.  Said invention increases the reliability of the repair and insulating operations.

Title: Polyacrylamide suspensions for soil conditioning
Inventor: ARNOLD CHARLES A
IPC: B02C13/282
Filed: 2002-04-26
Abstract: A stable aqueous suspension of water-soluble polyacrylamide particles is in a saturated solution of an ammonium salt. The polyacrylamide particles are characterized by a particle size of about - 150 mesh, and preferably - 270 mesh, with - 400 mesh most preferred. The suspension is at least about 2.5 % by weight polyacrylamide. When the ammonium salt is ammonium sulfate, PAM concentrations as high as about 15 % by weight can be achieved while still being easily flowable. The suspension is made by stirring the small particle PAM into the saturated ammonium salt solution. The PAM can be quickly dissolved to form a less concentrated PAM solution by adding the suspension to water or to a dilute solution, which can include calcium salts or other soil enhancers.

Patent CA-2474555-A1 (CA)
Inventor: URDAHL STEVEN GAGE
IPC: A61M39/14
Filed: 2003-02-03
Abstract: A method is disclosed for collecting and processing whole blood. Whole blood is collected at several remote donor sites and transported to a central bloo d- processing center, where information regarding demand for blood products is used to direct processing of whole blood into blood products. Whole blood is initially collected in collection bags unattached to satellite bags instead of commonly used multiple bag sets. When the determination is made at the blood processing center as to which blood products are to be made, the appropriate satellite bags and/or other system components are sterile docked to the bloo d- collection bag and the whole blood is processed. The use of blood-collection bags initially unattached to satellite bags eliminates waste and simplifies the transportation and processing of whole blood. Also disclosed are blood collection systems that remove leukocytes and collect whole blood into blood - collection bags unattached to satellite bags.
